My first check was not as positive unfortunately (granted, this is
only a single check).
I used IE and immediately got redirected to an additional challenge
(it looks like the CAPTCHA equates using IE with being a robot, I am
sure one could have entertaining speculations on that(.
The problem is that I was completely unable to find an alternative
audio captcha when prompted for the traditional one.
I very much like the fact that user analysis is replacing guessing
games, but for the fallback, Google needs to make sure that users have
at least the same options as they had before (i.e. audio captcha).
For the image matching, I wonder if the audio alternative could be a
soundfile, such as an animal sound, that user can then match to images
with descriptive alt texts.
If you select "audio captcha" and hear a "meow", you probably go look
for an image of a cat.
Obviously the image that is displayed and the image you have to match
to it cannot have identical alt texts, it would make for an easy
crack.
